AGK Engines Stuff Flashcards
Mags are dependant or independent of the aircraft battery?
Independent
Primary winding is also called and has?
Low tension
Low voltage, high current
Secondary winding is called and has?
High tension
High voltage, low current
Primary winding is continuously broken by
Contact breaker
Around which winding does the magnetic field collapse?
Collapse of the primary winding field causes a surge in the secondary winding
High voltage high tension cables feed electricity to the?
Spark plugs
Arcing causes damage where?
Breaker points
Capacitor is fitted how?
In parallel
Engine drives the
Contact breaker, distributor rotor and mag
Which circuit is earthed when off and how?
Primary circuit is earthed by closing
Closing to earth provides what?
Fail-safe in flight
Most light aircraft use what return?
Single pole
Impulse mag does what
Used on smaller and lower powered aircraft
Engine winds up a spindle which when released drives the mag
High tension booster coil does what?
Used on larger engines
Also known as shower of sparks
Current is fed from battery to help the engine start
Once started the HT booster coil is switched off
Low tension booster coil does what?
Uses aircraft battery to increase output from the mag
Fed to primary coil
